2024-02-28drm: tests: Fix invalid printf format specifiers in KUnit testsDavid Gow
The drm_buddy_test's alloc_contiguous test used a u64 for the page size, which was then updated to be an 'unsigned long' to avoid 64-bit multiplication division helpers. However, the variable is logged by some KUNIT_ASSERT_EQ_MSG() using the '%d' or '%llu' format specifiers, the former of which is always wrong, and the latter is no longer correct now that ps is no longer a u64. Fix these to all use '%lu'. Also, drm_mm_test calls KUNIT_FAIL() with an empty string as the message. gcc and clang warns if a printf format string is empty, so give these some more detailed error messages, which should be more useful anyway.

We're going to need a full-blown, functional, KMS device to test more components of the atomic modesetting infrastructure. Let's add a new helper to create a dumb, mocked, CRTC.

2024-02-20drm/tests/drm_buddy: fix build failure on 32-bit targetsLinus Torvalds
Guenter Roeck reports that commit a64056bb5a32 ("drm/tests/drm_buddy: add alloc_contiguous test") causes build failures on 32-bit targets: "This patch breaks the build on all 32-bit systems since it introduces an unhandled direct 64-bit divide operation. ERROR: modpost: "__umoddi3" [drivers/gpu/drm/tests/drm_buddy_test.ko] undefined! ERROR: modpost: "__moddi3" [drivers/gpu/drm/tests/drm_buddy_test.ko] undefined!" and the uses of 'u64' are all entirely pointless. Yes, the arguments to drm_buddy_init() and drm_buddy_alloc_blocks() are in fact of type 'u64', but none of the values here are remotely relevant, and the compiler will happily just do the type expansion. Of course, in a perfect world the compiler would also have just noticed that all the values in question are tiny, and range analysis would have shown that doing a 64-bit divide is pointless, but that is admittedly expecting a fair amount of the compiler. IOW, we shouldn't write code that the compiler then has to notice is unnecessarily complicated just to avoid extra work. We do have fairly high expectations of compilers, but kernel code should be reasonable to begin with. It turns out that there are also other issues with this code: the KUnit assertion messages have incorrect types in the format strings, but that's a widely spread issue caused by the KUnit infrastructure not having enabled format string verification. We'll get that sorted out separately.

Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference.

2023-11-14drm/format-helper: Pass format-conversion state to helpersThomas Zimmermann
Pass an instance of struct drm_format_conv_state to DRM's format conversion helpers. Update all callers. Most drivers can use the format-conversion state from their shadow- plane state. The shadow plane's destroy function releases the allocated buffer. Drivers will later be able to allocate a buffer of appropriate size in their plane's atomic_check code. The gud driver uses a separate thread for committing updates. For now, the update worker contains its own format-conversion state. Images in the format-helper tests are small. The tests preallocate a static page for the temporary buffer. Unloading the module releases the memory. v6: * update patch for ssd132x support v5: * avoid using unusupported shadow-plane state in repaper (Noralf) * fix documentation (Noralf, kernel test robot) v3: * store buffer in shadow-plane state (Javier, Maxime) * replace ARRAY_SIZE() with sizeof() (Jani) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Tested-by: Javier Martinez Canillas <javierm@redhat.com> # ssd130x Cc: Noralf Trønnes <noralf@tronnes.org> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: David Lechner <david@lechnology.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231009141018.11291-4-tzimmermann@suse.de
2023-11-09drm/tests: Remove slow testsMaxime Ripard
Both the drm_buddy and drm_mm tests have been converted from selftest to kunit recently. However, a significant portion of them are trying to exert some part of their API over a huge number of iterations and with random variations of their parameters. They are thus more a way to discover new bugs than actual unit tests. This is fine in itself but leads to very slow runtime (up to 25s for some drm_test_mm_reserve and drm_test_mm_insert on a Ryzen 7950x while running the tests in qemu) which make them a poor fit for kunit. Let's remove those tests from the drm_mm and drm_buddy test suites for now, and if it's ever needed we can always create proper unit tests for them later on. This made the entire DRM tests execution time (as of v6.6-rc1) come from 65s to less than .5s on a Ryzen 7950x system when running under qemu, and from 9 minutes to about 4s on a RaspberryPi4.

2023-11-08drm/dp_mst: Fix fractional DSC bpp handlingVille Syrjälä
The current code does '(bpp << 4) / 16' in the MST PBN calculation, but that is just the same as 'bpp' so the DSC codepath achieves absolutely nothing. Fix it up so that the fractional part of the bpp value is actually used instead of truncated away. 64*1006 has enough zero lsbs that we can just shift that down in the dividend and thus still manage to stick to a 32bit divisor. And while touching this, let's just make the whole thing more straightforward by making the passed in bpp value .4 binary fixed point always, instead of having to pass in different things based on whether DSC is enabled or not. v2: - Fix DSC kunit test cases.
